,Module Two,语法点的讲练,动名词,Grammar,动名词的定义,它是一种兼有动词和名词特征的非谓语动词形式。基本形式为:v-ing,动名词具有名词的性质，因此在句中可以做主语、表语、宾语、定语等。动名词有时态和语态的变化。,动名词的时态和语态的基本形式：（以write为例）,注意：动名词的否定形式是：not writing,V-ing形式的构成方式：,1.在一般情况下，在动词原形后直接加词尾 ing。eg.go going;do doing;ask asking;read-reading study studying;carry carrying;fly flying;worry worrying;2.在以不发音的e 结尾的动词后，去掉e，再加-ing。e coming live living dance dancing make making 3.在闭音节的单音节动词后、以重读闭音节结尾的多音节动词，而末尾只有一个辅音字母时，将这个辅音字母双写（x除外），然后再加 ing.sit sitting;run running;begin beginning;forget forgetting 4.在少数几个以 ie 结尾的动词后：须将ie 变作y，再加-ing。(这些动词词典一般均注明)eg.die dying;tie tying lie lying,动名词能在句中充当什么成分？,动名词的基本用法,用作主语所表动作比较抽象，或者泛指习惯性的动作。Playing with fire is dangerous.Climbing mountains is really
